The Distribution is shepherding Molecules@GNU-Darwin.org,
a repository of over 4 million small molecule structural coordinate files in PDB format, which is
accessible by FOSS molecule viewer software that is provided by the Distro, such as PyMOL and RasMOL.
over 50 million structures are in the pipe. Molecules@GNU-Darwin.org demonstrates the kind of great
work that can be done in the scientific and education fields with GNU-Darwin OS and free and open source software.
There are also some notes about the package
set and Molecules machine. Molecules of the Day has an

GNU-Darwin hard media

Key scientific software packages are now available on our Office and Package discs.
Favorite free software titles, first packaged for Darwin and Mac OS X by the Distribution, are included such as VIM, Ghostscript, Gnumeric, LaTeX, PyMOL (screenshot shown bottom left), Rasmol, gdFortran, LAM/MPI, AbiWord, GNUplot, and Raster3D. All are available for both x86 (Intel, AMD) and ppc (PowerPC) Darwin-only and Mac OS X systems.
Worry-free open source and command line installation is provided, and binary software distribution means that no compiling is necessary. Easy access to updates is also provided via our automated download system (ppc, x86).

As the premier free software distribution (founded Nov, 2000) for Darwin and Mac OS X, GNU-Darwin is clearly reliable with demonstrated stability and time-tested persistence. Our mature toolset has been successfully used for facilities administration, internet services, digital media production, intensive scientific calculation (see left center), authoring papers and progress reports (screenshot shown left top), high resolution graphics production, and all in a state of publication quality. With the assistance of a large open source development community, GNU-Darwin anticipates the needs of our users, and future Darwin utilities are provided in the present. GNU-Darwin is expressly engineered for high profile enterprises and cutting-edge scientific applications, but it is also suitable for workstation use and free software afficionados as well. Only with these discs, will users be up and running fast and getting real work done with all the desired tools, both now and in the future.

A number of key software offerings have been prepared for use with the GNU/Linux User
Tarball. The package manager software for GNU/Linux is not yet ready for
production, but these files should be ready to use. Just untar them in
~/usr/local, and try them with the parallel
computing examples. PyMOL is
also included.

I do
crystallographic consulting for
data
collection, refinement, and molecular
graphics; with
much synchrotron experience and particular expertise in the
Supper Mirror System. I'm also
a Physical Chemistry consultant specializing in water vapor equilibria in
medical devices. Please feel free to contact me, if you want my help in porting these programs to your Mac,
cheap laptops,
or anything else.
Here are links to my cv and NIH Biosketch.

Now you can do real science on your Mac! I have ported a variety of
scientific computing programs to Darwin. In order to facilitate this work
I have created a
Package Distribution
of Darwin and MacOSX software.
